Understanding Drywall Screws For Successful Installations

When it comes to building or renovating your home, there are a multitude of factors to consider. From choosing the right materials to ensuring that every detail is meticulously crafted, every decision plays a crucial role in the result. One such decision that often goes unnoticed but holds immense significance is the choice of drywall screws.

Drywall screws may seem like a minor component in the construction process, but they are, in fact, the secret ingredient to creating sturdy and robust walls. These small, often unnoticed, fasteners play a critical role in holding drywall panels firmly in place, preventing sagging, and providing overall structural integrity.


Drywall screws serve as a way to fasten whole or partial drywall sheets to either wooden or metallic studs. Moreover, screw failures that appear as strange concentric marks in outdated walls, can also be repaired with drywall anchor screws. Prior to the significant adoption of drywall screws, plasterboard was fastened in place using little, broad-based nails.
Though plasterboard nails remain in use as an inexpensive means to reinforce wallboard, drywall screws have emerged as the conventional method of securing drywall to combat nail-pop issues. Some of its significant benefits are:

• THREADED DESIGN: One of the key advantages of using drywall screws is their unique design. Unlike traditional nails, these screws are threaded and provide exceptional holding power. The threads effectively grip the drywall panel and the underlying framing material, securing them together firmly. The result is a wall that will remain intact for years to come, even in high-stress environments.

STRUCTURAL FLEXIBILITY: Another important aspect of drywall screws is their structural flexibility. These screws are specifically designed to accommodate the natural expansion and contraction of drywall due to temperature and humidity changes. The flexibility ensures that the walls remain stable under various conditions, reducing the risk of cracks or warping.

CUSTOMIZABILITY: Additionally, drywall screws offer greater customization options. Through different lengths and screws with or without drill points, they can be specifically selected to match the thickness and type of drywall being used. This allows for a more tailored and secure fastening solution, contributing to the overall durability and longevity of the walls.

EASE OF INSTALLATION: In terms of installation, drywall screws have a significant advantage over nails. The process of driving a screw into the wall is easier, faster, and provides better control and precision. With the right tools, such as a drill and a screwdriver bit, securing drywall becomes a breeze. This ease of installation translates into time and effort saved, ultimately leading to more efficient construction or renovation projects.


Full or partial sheets of drywall can now be fastened to wall frames or ceiling joints using drywall screws, which have grown to be the industry standard. It may initially seem complex to understand the lengths and sizes of drywall screws, as well as the types of thread, heads, and composition.

However, when it comes to self-service property renovation, this broad array of options reduces to only a handful of clearly defined options that function within the limited range of applications faced by homeowners in general. In the following paragraphs, we will go through the three key characteristics of plasterboard screws – length, gauge, and thread – along with the answers to a few FAQs.


On average, an extensive variety of dimensions are available for screws designed for construction. The purpose is that different construction supplies can have a wide variety of thicknesses. This is not the case with drywall.

In residential spaces, ½-inch-thick drywall tends to be the most popular. Although it happens infrequently, its thickness can occasionally rise or decrease by a minimum.

• Utilize 1 to 1 ¼-inch drywall screws with a ¼-inch drywall.
• Utilize 1 ¼-inch or 1 5/8-inch drywall screws with a ½-inch drywall.
• Utilize 1 5/8-inch or 2-inch drywall screws with a 5/8-inch drywall.

The only real occasion when DIY-ers will need to install a thicker drywall is when using type-x or fireproof drywall. Type-x drywall, used in warehouses and on walls next to furnace areas, is slightly denser (5/8 inch) to limit the dissemination of fire.

The front for ceilings and walls is occasionally made of ¼ inch thick drywall. It is bendable and may be manipulated to create curvatures. Nevertheless, nearly all the drywalls put up by self-renovators in cooking areas, showers, and other typical spaces will have a thickness of 1/2-inch.


Drywall screws are available in two different forms: coarse threaded and fine threaded.

• Drywall Screws with a Coarse Thread

For the majority of drywall and wood stud instances, coarse-threaded screws, sometimes referred to as W-type screws, are the most effective.

These broad threads do a fantastic job of grasping onto the wood and drawing the plasterboard up against the studs. The metallic burrs utilized for coarse-threaded screws might cause an injury to your fingertips; this is the only significant drawback. Therefore, operating with coarse-threaded drywall screws necessitates the use of gloves and other protective measures.

• Drywall Screws with a Fine Thread

Fine-threaded drywall screws work particularly well for attaching drywall to metal studs owing to their razor-sharp ends.

The metallic material frequently gets gnawed on through coarse threads, resulting in an inadequate traction. The fine-threaded drywall screws are self-threading and may be used with metallic studs, they additionally get referred to as S-type screws.


The gauge of a drywall screw is its measurement of diameter. Drywall screws in #6 or #8 are most often put to use.

One must be mindful that the screw’s diameter increases as the gauge numbers advances. This means that a #6 drywall screw would be narrower compared to a #8 drywall screw.

In addition, the gauge diameter is frequently stated as the 2nd digit following the length, for example #6 (0.1380-inch) or #8 (0.1640-inch). For instance, screw which is represented as “1/4-inch x 8” will be 1/4 inch in length and #8 in gauge value.


Since drywall screws are frequently supplied by pounds and an appropriate number of screws is required for the task at hand, determining the quantities to invest in might be tricky. When screws are priced for per pound, quantity is never certain, yet there are certain approximations:

• Around 200 screws with a 1-5/8-inch coarse thread and a #6 gauge.
• Around 238 screws with a 1-1/4-inch coarse thread and a #6 gauge.
• Around 92 screws with a 2-1/2-inch coarse thread and a #8 gauge.


The 1 1/4-inch or 1 5/8-inch, phosphate-coated, coarse-threaded drywall screws perform extremely well for the majority of projects using a ½ inch drywall attached to wood studs. Consider using the larger drywall screw for installing drywall in ceilings. Depending on your requirements, you can secure drywall in walls using either a long or short drywall screw.

Since drywall structure demands a huge number of attachments, this screw is economical and is offered in huge containers. Since there are still a lot of shafts exposed once the initial 1/2 inch of drywall has been addressed, it may be challenging to drive the 1 5/8 inch drywall screw. While this reduction in length facilitates screw driving, it also results in less retaining force.


A plasterboard screw gun is a specialized instrument for installing drywall. In comparison to most cordless drills, it is a lighter instrument working with less torque. However, you don’t have to invest in a special plasterboard screw gun if you’re performing a routine drywall installation owing to their constrained utility.
Some significant tips to consider when driving a drywall screw into the drywall are as follows:

• If your cordless drill lacks a clutch or a speed control that enables you to alter the torque, you are required to get one that does. You can avoid the nuisance of stripping the screw head by utilizing the clutch as a means to reduce torque.

• Use the screw’s pointy end to prick the drywall paper. On the head of the screw, insert the drill-driver bit, and initiate drilling.

• Allow the screw to insert itself into the stud and drywall. You will need to apply additional force about the halfway point. Otherwise, the screw head will be stripped.

• Once the head and paper are in uniformity with each other, stop.
Turn the screw one more time, either one-quarter or half of a turn, until it is just beneath the surface of the paper.

• Make sure that the paper doesn’t get torn during the process.


An inappropriate application of drywall screws is for building construction endeavors. This circumstance exists because wooden screws are far more expensive than drywall screws.

However, for quality construction, hardly any carpenter would ever employ drywall screws. Eliminating drywall screws is crucial when working on major construction projects, particularly when dealing with exterior construction like

fencing and patios.
The consensus is that drywall screws have a propensity to break easily. They usually snap as opposed to bending. Particularly vulnerable to shearing off are the screw heads, leaving behind a shaft part lodged in the wood.

Furthermore, the drywall screw’s curved point is intended to crease the drywall’s top paper layer, not to penetrate wood. This explains why drywall screws are breaking off so frequently when driven into wood. Ultimately, drywall screws are the ideal choice for plasterboard, small-scale construction projects or short-term constructions.

It is essential to note that quality matters when it comes to drywall screws. Opting for superior-quality drywall screws, such as those offered by United Gypsum, will ensure that you achieve the desired results.

Look for screws made from high-quality materials, such as hardened steel, that offer resistance against rust and corrosion. A well-designed screw head that allows for easy countersinking is also crucial, as it facilitates seamless finishing without the need for excessive putty or filler.

In conclusion

drywall screws may seem insignificant in the grand scheme of construction or renovation projects, but they are undeniably vital. Their ability to securely fasten drywall panels, accommodate structural movement, and provide customization options make them an indispensable tool for creating sturdy and long-lasting walls. So, the next time you embark on a DIY project or hire professionals, spare a thought for these unsung heroes of construction and choose the right drywall screws to fortify your walls.
